Add creating templates for checklists

Your tool is already awesome. we look forward to use it instead of "meistertask".
But we miss the feature to create templates for the checklists/todolists that can be used with the cards.
And then multiple checklists per Card maybe....

This would save huge amount of time and asure consistency

Best regards
